Calcium Carbonate To Calcium Oxide

Calcium oxide is usually made by the thermal decomposition of materials such as limestone or seashells that contain calcium carbonate ceCaCO3 mineral calcite in a lime kiln. This is accomplished by heating the material to above 825 C 1517 F a process called calcination or lime-burning to liberate a molecule of carbon dioxide
